The consequence of a contract having contingencies is that it is:

A contract with contingencies introduces specific conditions that must be met for the contract to become fully enforceable. These contingencies can include aspects like financing approval, satisfactory inspections, or the sale of another property. If these conditions are not satisfied, the parties involved often have the option to void the contract without penalty.

This is why the correct answer is that a contract with contingencies is possibly voidable. It hinges on the satisfaction of the contingencies, and the absence of those conditions allows one or both parties the right to back out of the agreement without consequence. The other options suggest certainty and unqualified enforceability, which would not apply in the context of a contract laden with conditions that may or may not be fulfilled.
